Auditing with spring-data-mongodb

Question

I am trying to enable auto audit fields with spring data mongodb as explained here. Below is my configuration class

@Configuration
@EnableWebMvc
@ComponentScan(basePackages = "com.abc")
@EnableMongoRepositories(basePackages = "com.abc.xyz.repository")
@EnableMongoAuditing
public class ApplicationConfiguration {

    @Bean
    public MongoDbFactory mongoDbFactory() throws Exception {
        ServerAddress serverAddress = new ServerAddress("127.0.0.1", 27017);
        MongoCredential mongoCredential = MongoCredential.createCredential("user", "test", "abc123".toCharArray());
        MongoClient mongoClient = new MongoClient(serverAddress, Arrays.asList(mongoCredential));
        return new SimpleMongoDbFactory(mongoClient, "test");
    }

    @Bean
    public MongoTemplate mongoTemplate() throws Exception {
        return new MongoTemplate(mongoDbFactory());
    }
}

But when I add @EnableMongoAuditing, I am getting the below error on starting the server.

Caused by: java.lang.RuntimeException: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'mongoAuditingHandler': Cannot create inner bean '(inner bean)#6dca0c34' of type [org.springframework.data.mongodb.config.MongoAuditingRegistrar$MongoMappingContextLookup] while setting constructor argument; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name '(inner bean)#6dca0c34': Unsatisfied dependency expressed through constructor parameter 0: No qualifying bean of type [org.springframework.data.mongodb.core.convert.MappingMongoConverter] found for dependency [org.springframework.data.mongodb.core.convert.MappingMongoConverter]: expected at least 1 bean which qualifies as autowire candidate for this dependency.

Answer 1

1 : Make sure you have spring-data-mongodb

2 : if you are using @CreatedDate or @LastModifiedDate then you don't need any additional configuration.

class ClassName {

    .......

  @CreatedDate
  private DateTime createdDate;

  @LastModifiedDate
  private DateTime @lastModifiedDate;

}

3: if you are using @CreatedBy and @LastModifiedBy then you have to implement AuditorAware<T> SPI interface

class ClassName {

    .......

    @CreatedBy
    private String createdBy;

    @LastModifiedBy
    private String lastModifiedBy;

}

public class AppAuditor implements AuditorAware<String> {

    @Override
    public String getCurrentAuditor() {

        // get your user name here
        return "xxxx";
    }

}

Implementation of AuditorAware based on Spring Security from spring doc

class SpringSecurityAuditorAware implements AuditorAware<User> {

  public User getCurrentAuditor() {

    Authentication authentication = SecurityContextHolder.getContext().getAuthentication();

    if (authentication == null || !authentication.isAuthenticated()) {
      return null;
    }

    return ((MyUserDetails) authentication.getPrincipal()).getUser();
  }
}

Answer 2

Can you check if you have Spring Data MongoDB dependency 1.9.4.RELEASE or above as mongoAuditingHandler requires MappingMongoConverter which is available in version 1.9.4.RELEASE or above as per changelog - spring-data-mongodb-changelog, for example:

<dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-mongodb</artifactId>
    <version>1.9.4.RELEASE</version>
</dependency>
